Bike parts research

I'm doing some research for a product design project based on specialized bikes. If you could give me some answers it would be great!

Is there anything that you would like on a bike that isn't already available? Is there something that annoys you when riding that you think could be improved? And do you think there is a gap in the market anywhere? And if so where?

And Jameso, not a brief just a few questions that might be able to help me find anything that could lead to a product idea really, you know stuff like, longer pedals or more ergonomics bars. Stuff like that

There are no easy pickings in bike product innovation, ISTM. 650b is a cry for help, really. A creatively bankrupt step from an industry that cannot picture the future of mountain biking. (in part because it looks like the present).

A dropper seat post that uses the frame/seat tube as the cylinder for the uppy-downy piston-thingamy.

When you think about it it is slightly preposterous fitting a thing-within-a-thing-within-a-thing to allow the seat to move up and down, when it could simply be a thing-within-a-thing (the seat tube)..
